Sea Ice Duration

Annual Duration of Expanding and Receding Sea Ice

Surprisingly, unlike Minnesota lakes, the duration of sea ice expansion and recession in either the northern or southern hemisphere hasn’t really changed over the last 30 years. However, even though durations haven’t changed, we’ve shown from other plots that sea ice is expanding less and receding more when it does happen.

Sea Ice, Temperature, and Sea Level

Relationship between Sea Ice and Temperature

These two temperature plots show the significant effect that global mean temperature change has had on the extent of global sea icem and, even more, on the presence of anomalies in global sea ice.

Sea Ice and Temperature Comments

This plot shows the significant effect that even a small decline in global sea ice has with a rise in global sea level. While their are certainly other effects at play that contribute to a rise in sea level, such as global temperature, it’s interesting nonetheless. It’s important to note that because of data obtained, this plot represents sea ice and levels during the month of March.
